Answer:
7/12 of the students
Step-by-step explanation:
So first you would need to get your fractions to have the same denominator. When your trying to get your fractions to get the same denominato. You must multiply both the numerator and denominator.
The most common denominator from 1/4 and 1/3 is 12. So you multiply both the numerator and denominator of 1/4 by 3. So then your new fraction is 3/12. Now you multiply 1/3, both numerator and your denominator by 4. Then your new fraction is 4/12. So The last step is to add both of your numerators. Never add the denominators together. And at last you have your answer. 7/12.

Answer:
k² + 10k + 24
Step-by-step explanation:
First, the square has side length k. Now in rectangle,
l= k+6
b= k+4
Ar. of rectangle= l×b
Eq.
(k+6)(k+4)
opening bracket,
k² + 6k + 4k + 24
k² + 10k +24
The addition property of equality. It says that if you add the same number to each side of the equation, the two sides of the equation will be equal. In this case, the number 8 was added to each side.
